Esterification of Sucrose Chelates by Acid Anhydrides and Chlorides. Acetic, caprylic, stearic, maleic or phthalic acid anhydrides were added to a N,N-dimethylformamide (DMF) solution of a sucrose chelate in ratios of sucrose anhydride 1 1,3 or 1 3. 

The reaction mixture was allowed to stand with acetic anhydride for 15 h at 22°c, with caprylic and stearic anhydride for 3 h at 60°c, or with maleic and phthalic anhydride for 10 h at 60°c. The isolation, e.g. of monostearates, was made by extraction with 1-butanol ( ) after addition of 10% aq sodium chloride to the DMF.

Phthalates, made by - esterification of phthalic acid anhydride with two moles of an alcohol (C7-C13), are the laigest-volume plasticizers for PVC. The alcohols are predominantly of petrochemical origin (e.g., ethylhexanol). However, straight-chain alcohols, such as octanol (- caprylic alcohol) or decanol (- capric alcohol), which can be derived from RR, are also used. Esters of these have better low-temperature performance and a lower viscosity than the branched-alcohol phthalates. Their lower volatility has led to their application in flexible PVC, especially in the automotive industry, to avoid fogging , which is the unwanted condensation of plasticizers on the windshield. These properties often compensate for their higher price. Do-decanol is employed in phthalates, where good high-temperature performanee is demanded.
